Those free earphones you got when you changed bank accounts back in 2009?
Ditch them. They're muck. Worse than muck, in fact; they're ruining your musical experience on a daily basis.
You don't need to blow a week's wages to track down a decent set though - you can pick up some seriously impressive little sound canons for the same as a round at that inhibitively expensive pub your mates insist on going to every Friday.
Having plugged a range of affordable earphones into our, well, ear holes, we've picked out our favourites for under £30. Happy listening.
